Do Contact Lenses Expire? Everything Eye Doctors Want You to Know About Replacing Your Contacts

If you wear contact lenses, you probably don't think much about them. But they're a relatively new invention -- in fact, the first disposable contact lens wasn't introduced until 1982. "We think of contact lenses as being so normal, but 100 years ago, nobody walked around with little pieces of plastic over their eyes," says ophthalmologist Dr. Robert Kinast, the vice chair of ophthalmology at Legacy Devers Eye Institute and co-founder of GentleDrop. "Contact lenses are foreign bodies and should

Apple exempt from Corning’s EU antitrust probe deal

The European Commission has concluded an antitrust investigation into Corning’s glass supply deals. And for once, Apple just watched from the sidelines. Apple not part of the relevant market The European Commission has accepted a series of commitments from Corning, wrapping up an investigation over potentially anticompetitive practices involving the supply of its famous Gorilla Glass (officially called Alkali-aluminosilicate glass, or ‘Alkali-AS Glass’), used in the cover layer of smartphones,

TSMC to start building four new plants with 1.4nm technology

TSMC to start building four new plants NEXT GENERATION: The four plants in the Central Taiwan Science Park, designated Fab 25, would consist of four 1.4-nanometer wafer manufacturing plants, TSMC said By Huang Hsu-lei, Hung You-fang and Jake Chung / Staff reporter, with staff writer Taiwan Semiconductor Manufacturing Co (TSMC, 台積電) plans to begin construction of four new plants later this year, with the aim to officially launch production of 2-nanometer semiconductor wafers by late 2028,

Make Your Own Backup System – Part 1: Strategy Before Scripts

Backup: Beyond the Simple Copy For as long as I can remember, backup is something that has been underestimated by far too many people. Between flawed techniques, "Schrödinger's backups" (i.e., never tested, thus both valid and invalid at the same time), and conceptual errors about what they are and how they work (RAID is not a backup!), too much data has been lost due to deficiencies in this area. Nowadays, backup is often an afterthought. Many rely entirely on "the cloud" without ever asking

Scientists Say That Uranus Appears to Have a Girlfriend

When checking out Uranus, scientists discovered something exciting: that the planet appears to have a long-term... well, call it a situationship. In a new, yet-to-be-peer-reviewed paper flagged by Universe Today, an international group of researchers detailed finding a so-called "Centaur" — a small, icy and rocky body that sits between Uranus and Neptune and is designated as a minor planet — that appears to have been keeping up with Uranus in a delicate cosmic dance for thousands or even millio

For-Profit Hospital Chain Reportedly Left Patient Lying in Pool of His Own Blood

Image by Getty / Futurism For-profit rehabilitation hospitals are booming in the United States, but their rapid growth is leaving patient safety far behind. The US post-acute care industry, which deals with rehab and long-term care facilities, was worth an estimated $483 billion in 2024, and is expected to grow to over $785 billion by 2034. On paper, it's easy to assume all that business potential would translate to quality care. Unfortunately, for thousands of patients across the country, th

A 14kb page can load much faster than a 15kb page (2022)

Why your website should be under 14kB in size Why your website should be under 14kB in size Having a smaller website makes it load faster — that's not surprising. What is surprising is that a 14kB page can load much faster than a 15kB page — maybe 612ms faster — while the difference between a 15kB and a 16kB page is trivial. This is because of the TCP slow start algorithm. This article will cover what that is, how it works, and why you should care. But first we'll quickly go over some of the

Mapping the Margins: The Internet's Invisible Hand in Reproductive Care

We don’t often think about the internet as being good for our health. In fact, “internet” and “health” are primarily related in a negative context in online spaces -- we’re getting too much screen time, we’re “chronically” online, etc. It may come as a surprise, but access to the internet is commonly recognized as a "super" determinant of health. Limited internet access has been linked to high mortality rates during the COVID-19 pandemic, and having the internet in easy reach means we can stay

The Best Protein Bar: 5 Dietitians Explain Which Ingredients to Look For

Even though many people already get all the protein they need every day, having on-the-go snacks such as protein bars can be helpful when you're in a pinch. With so many protein bars on store shelves, finding the best one for your tastes and preferences can be difficult and overwhelming. But whether you’re hiking, commuting or just packing light, a good snack -- and maybe a compact Bluetooth speaker -- can make the journey more enjoyable. To help narrow down the selection, I consulted dietitian

The Art of Freelancing Like a Boss, According to the Folks Who Do It

Jeffrey Hazelwood/CNET Jamie Brindle has been freelancing for 16 years and is on a mission to "demystify" the freelance world. In 2020, amid a shaky job market and widespread rejection of corporate hustle culture, he started helping beginner freelancers become their own bosses. The expansion of remote work, advances in AI and the growth of influencer platforms have all led to a kind of self-employment boom. As Gen Zers and millennials find new ways to upgrade their skills in a flexible work se

RFK Jr. wants to change program that stopped vaccine makers from leaving US market

This story was originally published by ProPublica. Five months after taking over the federal agency responsible for the health of all Americans, Robert F. Kennedy Jr. wants to overhaul an obscure but vital program that underpins the nation’s childhood immunization system. Depending on what he does, the results could be catastrophic. In his crosshairs is the Vaccine Injury Compensation Program, a system designed to provide fair and quick payouts for people who suffer rare but serious side effe

How to Delete All of Your Social Media Accounts: Instagram, X, Facebook, TikTok, and More

Here’s an evergreen take: There has never been a better time to get off social media. Social services have evolved even further into becoming sticky traps for doomscrolling and AI-generated slop, and are hitherto unprecedented frontiers for rage bait. Bummed out about all the misinformation and being part of a profit machine that funds one increasingly unhinged billionaire or another? Well, there’s a way out. Unfortunately, social media companies don’t always make it very easy to rescind their

How to design an actually good flash flood alert system

Flash floods have wrought more havoc in the US this week, from the Northeast to the Midwest, just weeks after swollen rivers took more than 130 lives across central Texas earlier this month. Frustrations have grown in the aftermath of that catastrophe over why more wasn’t done to warn people in advance. Local officials face mounting questions over whether they sent too many or sent too few mobile phone alerts to people. Some Texans have accused the state of sending out too many alerts for injur

OpenAI, Anthropic, Google may disrupt education market with new AI tools

AI companies could soon disrupt the education market with their new AI-based learning tools for students. BleepingComputer recently reported that OpenAI is working on a Study Together feature for ChatGPT. This would allow ChatGPT to teach students a wide range of topics and then offer quizzes. The idea is to create an engaging and interactive "study together" experience where students ask questions and ChatGPT puts in effort to teach them. But it turns out that OpenAI isn't the only AI compa

Cats as Horror Movie Villains

Do people like watching cats because of neoteny? I doubt it, because adult cats don’t look at all like babies. But then why do we have this odd fascination with every ordinary action of a cat and treating them as instances of a Platonic Cat? I speculate that there may be an evolutionary psychology reason: cats in Africa prey on primates to a degree I suspect few people appreciate, and this seems to have been true for millions of years, making them our apex predator. So perhaps we are still sligh

WhatsApp streamlines in-app support process

If you’ve ever tried to get in-app support on WhatsApp, you know the process used to start with filling out a form, possibly attaching a few files, and waiting for a support rep to eventually get in touch. Now, that form is on its way out, and the screening process is, you guessed it, becoming AI-based. But that’s not necessarily a bad thing. Out with the form, in with AI Unless you’re Stephen Hackett, support knowledge bases are never fun to navigate, especially if you are in a hurry and alr

The Israeli "art student" mystery (2002)

In January 2001, the security branch of the U.S. Drug Enforcement Agency began to receive a number of peculiar reports from DEA field offices across the country. According to the reports, young Israelis claiming to be art students and offering artwork for sale had been attempting to penetrate DEA offices for over a year. The Israelis had also attempted to penetrate the offices of other law enforcement and Department of Defense agencies. Strangest of all, the “students” had visited the homes of n

Netflix’s first show with generative AI is a sign of what’s to come in TV, film

Netflix used generative AI in an original, scripted series that debuted this year, it revealed this week. Producers used the technology to create a scene in which a building collapses, hinting at the growing use of generative AI in entertainment. During a call with investors yesterday, Netflix co-CEO Ted Sarandos revealed that Netflix's Argentine show The Eternaut, which premiered in April, is "the very first GenAI final footage to appear on screen in a Netflix, Inc. original series or film.” S

Anthropic tightens usage limits for Claude Code — without telling users

Since Monday morning, Claude Code users have been hit with unexpectedly restrictive usage limits. The problems, many of which have been aired on Claude Code’s GitHub page, seem to be concentrated among heavy users of the service, many of whom are on the $200-a-month Max plan. Users are only told “Claude usage limit reached,” and given a time (typically within a matter of hours) when the limit will reset. But with no explicit announcement of a change in limits, many users have concluded that the

Scientists prove Android Earthquake Alerts system actually works pretty well

Google TL;DR Google’s Android Earthquake Alerts system crowdsources data from smartphone accelerometers to detect seismic activity. The system has detected over 18,000 earthquakes and alerted millions across nearly 100 countries. Users receive crucial seconds of warning, enabling them to take protective action before shaking begins. Google introduced Earthquake Alerts for Android devices back in 2020, and expanded the feature to cover all US states in September 2024. More recently, Google al

WhatsApp should prepare to stop operating in Russia, official says

A Russian lawmaker who regulates the IT industry said WhatsApp should prepare to stop offering its services in the country. Anton Gorelkin, the deputy head of the lower house of parliament's IT committee, said that it's very likely that WhatsApp will be placed on a list of restricted software, as Reuters reports. WhatsApp owner Meta is designated as an extremist organisation in Russia, which has banned Facebook and Instagram since 2022. This week, President Vladimir Putin issued a directive for

Psilocybin decreases depression and anxiety in cancer patients (2016)

Participants with a potentially life-threatening cancer diagnosis and a DSM-IV diagnosis that included anxiety and/or mood symptoms were recruited through flyers, internet, and physician referral. Of 566 individuals who were screened by telephone, 56 were randomized. Figure 1 shows a CONSORT flow diagram. Table 1 shows demographics for the 51 participants who completed at least one session. The two randomized groups did not significantly differ demographically. All 51 participants had a potentia
